Steam Disk Write Error While Downloading/Upgrading

Usually, when installing or updating a popular Steam game, such as Dota Underlords, Football Manager, Kenshi, Tree of Savior, and Team Fortress, you may encounter an error that suggests a Steam disk write error or perhaps disk read error. You can refer to the error details and related screenshots.

As you can tell, the extra information in the parenthesis behind the detailed error message is disk related. This issue can occur anytime when a game is updated or installed on Steam. Then, Steam becomes unable to complete the installation. Thus, to have Steam disk problems solved, you need to take prompt actions to repair the hard drive in question.

Fix 1. Restart Steam and Computer to Fix the Disk Write Error 

No matter when you stuck in trouble, restarting can always help you. For example, the computer blue screen, black screen, disk error, etc., and Steam disk error is no expectation. The first thing you should try is to restart Steam and PC.

To restart Steam:

Step 1. Open any Steam window.

Step 2. In the top-left corner, click the word "Steam" to open a drop-down menu.

Step 3. From the drop-down menu, select "Exit" (Windows) or "Quit Steam" (Mac). Steam will close.

Step 4. Open Steam again, and log back in if you've been logged out.

restart steam

Then, you can try again to see if the disk read error or write error happens again.

To restart PC:

Step 1. Click the "Start" icon.

Step 2. Go to "Shut down or sign out > Restart."

Fix 2. Clear Steam Download Cache to Fix Disk Error

Another way to fix the error is to clear the download cache. This operation forces the Steam client to flush locally cached configuration data and acquire it from the Steam server again.

To clear Steam download cache:

Step 1. Open "Steam", go to "Settings".

Step 2. Click "Downloads", and select "Clear Download Cache".

After that, try to reopen Steam and see if it works.

Fix 3. Check and Repair Steam Disk Bad Sectors

If there are bad sectors on your Steam drive, you may also encounter the disk write error related to Steam, Origin, or other games. Then, you should check if there are bad sectors on your drive.

1 - Check Bad Sectors on the Steam Disk

Starting from this approach, you'll need additional help from a third-party free partition manager tool, which is EaseUS Partition Master. First of all, the Surface Test feature is extremely easy-to-use in checking bad sectors. Follow the steps below to check the bad sectors.

Your Reliable Choice - EaseUS Partition Master

Step 1. Download EaseUS Partition Master and install it. Right-click the disk that you want to check, and then click "Surface test".

click surface test

Step 2. The operation will be immediately performed. Bad sectors will be marked as red.

wait for the process to check your sectors

If no error is found, go back to Steam and see if the Steam game update is stuck still.

2 - Replace Failing Steam Hard Drive

If you find some error, which is responsible for the Steam downloading/upgrading error, it is a nice choice to clone the drive to another HDD and replace the drive. Fortunately, EaseUS Partition Master can also make it.

To replace a failing hard drive with a new one, use EaseUS Partition Master's clone disk function:


Step 1: Select the source disk.

Open EaseUS Partition Master. Right-click the disk that you want to copy or clone. Then, select "Clone".

select the disk that you want to copy

Step 2: Select the target disk.

Choose the wanted HDD/SSD as your destination and click "Next" to continue.

choose a suitable destination

Step 3: View the disk layout and edit the target disk partition size. 

Then click "Continue" when the program warns it will wipe out all data on the target disk. (If you have valuable data on the target disk, back up it in advance.)

confirm to continue the cloning process

You can select "Autofit the disk", "Clone as the source" or "Edit disk layout" to customize your disk layout. (Select the last one if you want to leave more space for C drive.)

Adjust disk layout

Step 4: Execute the operation.

Click the "Execute the operation" option and click "Apply" to start the disk cloning process.

Fix 4. Run Steam as an Administrator to Fix It

There are times when you are not an administrator, and you can not get access to specific applications. Running software as an administrator gives it extra permissions and can fix several odd problems.

Step 1. Navigate to your Steam folder and right-click Steam.exe, click "Properties"

Step 2. Select the "Compatibility" tab.

Step 3. Under Privilege Level, check "Run this program as an administrator".

Step 4. Click "Apply > OK".

run steam as administrator

Fix 5. Move Steam Game Folder to Another Drive

Another effective way to solve Steam disk write error is by moving Steam to another healthy drive. A manual copy cannot guarantee the result. All you need is EaseUS Todo PCTrans. It provides Steam users with three practical game transfer modes: PC to PC, Image Transfer, and App Migration. Each makes it the best overall Steam game transfer tool to move a PC game to another drive automatically.

To transfer Steam games to another drive:

Step 1. Connect the destination drive to your computer.

Step 2. Choose the games you want to change the location.

Step 3. Transfer the games to the destination drive.

Fix 6. Verify Integrity for Steam Game Files

Try to verify integrity for Steam games files at first if you see games keep crashing or their models missing unknowingly.

Step 1. Reboot system and then launch Steam.

Step 2. Select the "LIBRASY" tab and right-click the game that sends disk errors and select "Properties".

Step 3. Click the "LOCAL FILES" tab, and then you can see "VERIFY INTEGRITY OF GAME FILES…" button. Click it.

Step 4. Steam starts verifying game files, which may take a couple of minutes. Please note that some files may fail to verify, which is normal for most Steam games. That's because these files are local configuration files, and they cannot be disturbed as part of this action.

Step 5. When all files are validated successfully, you can retry installing updates and see whether the disk error is removed.

verify steam integrity

Fix 7. Remove Write Protection from the Steam Drive

When a disk is written-protected, you're prevented from modifying it, such as formatting, writing data, or installing programs. That's the other possible reason why you receive disk errors on Steam. Simply use the diskpart command to clear write protection and remove the error.

Step 1. Press "Win + R", type cmd to open "Command Prompt".

Step 2. Type diskpart and hit "Enter".

remove write protection

Step 3. Type list disk and hit "Enter".

list disk

Step 4. Type select disk 0 (Replace 0 with the write-protected device number) and hit "Enter".

Step 5. Type attributes disk clear readonly and hit "Enter".

Step 6. Type exit to close the diskpart window once the write protection removing process is finished.

Restart your PC and check if you can access your Steam again.

If you are not professional in computing management and not familiar with command lines, don't worry. EaseUS R&D team has promoted a fresh kit for helping you resolve the write-protection issue on your hard drive, external hard drive, USB or SD card, etc., devices.

EaseUS Tools M is a practical computer fixing tool that is safe and light-weighted. It's a perfect alternative to the command line. 

Use this one-click tool to solve the write-protection issues on your own:

Step 1: DOWNLOAD and install EaseUS Tools M for free.

Step 2: Run EaseUS Tools M on your PC, choose the "Write Protection" mode.

Step 3: Select the device which is now "Write-Protected" and click "Disable" to remove the protection.

Remove Write Protection from storage devices.

Fix 8. Remove Disk Write Error by Reinstalling Steam

If you still cannot fix Steam disk write error in windows 10, 8.1, 8, 7, you should reinstall Steam. Reinstalling Steam can resolve potential issues with Steam client and service files. However, this process will remove Steam and any installed game content from your machine. 

To Uninstall Steam:

Step 1. Exit Steam. Move the Steamapps folder out of C:\Program Files\Steam to keep game installations.

Step 2. Click the Windows Start button and select "Control Panel".

Step 3. Open the "Add" or "Remove Programs" dialog. Select "Steam" from the list and click the "Change/Remove" button

Step 4. Select the Automatic option and click "Next".

Step 5. Click "Finish" to uninstall Steam

To Install Steam:

Step 1. Visit https://store.steampowered.com/about/

Step 2. Click the "Install Steam" button and allow the Steam installer to download.
